Comparative Study on the Efficacy of Precise Radiotherapy in Lymphatic Drainage Area of Esophageal Cancer between Preventive Radiation and Invasive Field Radiation

Altern Ther Health Med. 2023 Oct 27:AT9045. Online ahead of print.


To investigate the efficacy of precise radiation therapy for lymphatic drainage area prevention (ENI) and invasive field irradiation (IFI) in patients with esophageal cancer undergoing radical radiotherapy. A retrospective analysis was conducted on 96 esophageal cancer patients admitted to our hospital from March 2018 to March 2021 who underwent radical radiotherapy. Among them, 48 patients who received precise radiation therapy to prevent radiation in the lymphatic drainage area were included in the ENI group, and 48 patients who received field irradiation were included in the IFI group. Compare and analyze the total clinical response rate, local control rate within 3 years after treatment, survival rate, and incidence of adverse reactions after radiotherapy between two groups of patients. There was no statistically significant difference in the total clinical response rate between the ENI group and the IFI group after radiotherapy (P > .05). There was no statistically significant difference in local control rate and survival rate between the ENI group and the IFI group within 3 years of treatment (P > .05). The incidence of postoperative complications in the ENI group was significantly higher than that in the IFI group, with a statistically significant difference (P < .05). When giving radical radiotherapy to esophageal cancer patients, the clinical total effective rate, survival rate, and local control rate of involving field irradiation are equivalent to the preventive radiation effect of precise radiotherapy for lymphatic drainage area. Besides, involving field irradiation can reduce the incidence of adverse reactions in patients after radiotherapy, which has high clinical value.
